Bacterial spot is a serious plant disease that commonly affects peppers. If advanced enough, bacterial spot can cause leaf drop and raised scab-like lesions on the peppers that make them unattractive and unmarketable. And if one plant is infected, all of the others are likely to follow. Bacterial spot is highly contagious and it can even be spread by errant rain drops splashing from an infected plant to a healthy one. The best way to prevent against bacterial spot disease is to start with healthy pepper seeds that have been properly prepared and sterilized.
Heat water in your pot until a thermometer reaches and rests at 125 degrees Fahrenheit.
Pour the pepper seeds into the pot. Stir them every few minutes as they soak for 30 minutes.
Prepare a large bowl of ice water while the pepper seeds soak.
Spoon the seeds out of the hot water and into the ice water bath. Only leave them there for a few moments, until they are cool to the touch.
Dry the pepper seeds. Spread them out over a paper towel so that none of them are overlapping. Then store them in a cool, dry place that is out of direct sunlight. Turn them over once a day to make sure that they dry evenly. The seeds are sufficiently dry and ready for planting when they are light and brittle. This may take 1 week or more.
